As Eli pointed out (and I got wrong in the first place), langref says: "The getelementptr returns a vector of pointers, instead of a single address, when one or more of its arguments is a vector. In such cases, all vector arguments should have the same number of elements, and every scalar argument will be effectively broadcast into a vector during address calculation." Costantfold for gep doesn't really take in account this paragraph, returning a pointer instead of a vector of pointer which triggers an assertion in RAUW, as we're trying to replace values with mistmatching types.
